9 Claims, 3 Drawing Figures PATENTED HAY20|975 SHEET 20F 2 1 URINARY COLLECTION DEVICE BACKGROUND OF THE INVENTION This invention relates to a urinary collection device and more particularly, to a urinary collection device for use with the ileal conduit.

In surgery, frequently it is necessary to bypass the functioning of the bladder and directly draw the urine produced by kidneys out of the body through the ileal conduit. During surgery, an everted ileal bud is formed which lies slightly above the skin level of the patient so as to form a conduit for the urine being eliminated.

Conventional devices presently available utilize a collection bag and a connecting apparatus which causes the opening of the bag to be in proximate location with the projecting portion of the ileal conduit. An adhesive surface generally circular in shape is formed around the opening in the collection bag and the adhesive surface is attached to the skin of the stomach of the patient around the ileal conduit. Unfortunately, due to the nature of the characteristics of the urine, frequently, the adhesive becomes loosened and significant leakage can occur. As can readily be understood, this is not only uncomfortable for the patient but also causes extreme difficulties from a sanitary standpoint as well. Further, repeated and frequent changes of the prior art collection bags are required in order to maintain safe, sanitary and comfortable conditions for the patient.

In addition to the above disadvantages, the use of the adhesive surface against the skin of the patient in order to secure the collection bag in place can often cause patient discomfort and skin abrasion. Further, the patients activities can be severely hampered because of the poor adhesion between the collection bag and skin of the patient.

An object of this invention is to provide a urinary collection device for collecting urine eliminated through the ileal conduit in an improved fashion which eliminates the above disadvantages.

Another object of this invention is to provide such a collection device which is inexpensive to manufacture, simple to use and efficient in operation.

Still another object of this invention is to provide such a collection device which prevents leakage of urine.

Another object of this invention is to provide such a collection device which frees the patient from the restricted activities previously encountered.

Yet another object of this invention is to provide such a collection device which is readily suitable to be used after surgery and the like.

Other objects, advantages and features of this invention will become more apparent from the following description.

SUMMARY OF THE INVENTION In accordance with the principles of the invention, the above objects are accomplished by providing a urinary collection device for collecting urine eliminated through the ileal conduit which comprises a collection bag and a conduit directly connecting the ileal conduit to the collection bag. In one embodiment, the conduit is formed of a rubbery material and is adapted to fit within the ileal conduit forming a secure seal between the outer surface of the conduit means connecting the bag to the ileal conduit and the inner wall of the ileal conduit. The conduit means is provided with a projection means insertable in the ileal conduit and means are provided to maintain the projection means in that position. The formation of a seal between the projection means and the ileal conduit permits efficient elimination of the urine developed in the body of the patient without the previously discovered leakage situation.

As another embodiment of the invention, a spacer means is provided between the bag and the skin of the patient so as to allow the collection device to accommodate to the skin of the stomach of the patient and prevent the bag from touching the ileal bud. Further, the end of the projection member inserted in the ileal conduit can be bulbous in form and will be squeezed together while being inserted in the ileal conduit. When fully inserted, the bulbous distal end will open allowing the projection member to be securely retained in the ileal conduit without fear of it be loosened. As can be understood, the projection member is formed of a material which is as soft as, and perhaps even softer than, the ileal conduit to prevent damage thereto. The distal end of the projection member, as described, is soft and distensible and returns to its original enlarged configuration when fully inserted in the ileal conduit.

In operation, it has been found that the present invention provides significant advantages over that found with prior art, especially as indicated above.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the urinary collection device of this invention being inserted in the ileal conduit;

FIG. 2 is a sectional view illustrating the connection between the urinary collection device of this invention and the ileal conduit; and

FIG. 3 is a perspective view of another embodiment of this invention.

DETAILED DESCRIPTION Referring to FIG. 1, there is shown the ileal conduit 10 slightly raised above the surface of the skin 12 of the patient, approximately 1 centimeter. The raised portion is known as the above-mentioned ileal bud. The urinary collection device 14 is comprised of a collection bag 16 and an integrally formed projection member or conduit 18. The distal end of the conduit member 18 is inserted in the ileal conduit 10 to form a direct conduit between the ileal conduit 10 and the collection bag 16. The projection member 18 is formed of a rubbery material such as rubber, plastic or the like which is soft enough to fit within the ileal conduit 10 yet form a seal therein. In particular, ,the outer wall 20 of the conduit or projection member 18 forms a seal with the inner wall 22 of the ileal conduit so as to prevent leakage of urine as it passes from the ileal conduit 10 to the collection bag 16.

In order to maintain the projection member 18 within the ileal conduit 10, strap means 24 may be employed, these strap means being attached to projecting ears 26 formed integrally with the collection device 14. The strap 24 is adapted to fit around the body of the patient. In another form, a spacer means 28 is provided, the spacer means being integrally formed with the collection bag 16 and adapted to accommodate the surface of the skin of the patient as indicated in FIG. 2. As can be seen, the spacer member 28 is hollow and maintains the ileal bud 11 a distance away from the bag 16 to prevent the bag touching the ileal bud. The surface 30 of the spacer contacting the skin of the patient may be provided with an adhesive to secure the conduit or projection member 18 within the ileal conduit 10.

Referring to FIG. 3, there is shown yet another embodiment of this invention in which the distal end 32 of the conduit or projection member 18 is provided in a bulbous form, that bulbous shape being squeezed as the projection member is inserted in the ileal conduit 10. When fully inserted, the bulbous member again expands securing the conduit or projection member 18 in place within the ileal conduit for self-retaining therein. The distensible enlarged distal end enables this self-retaining feature to be achieved.

In one embodiment, a nipple, similar to that found with baby bottles was used as the projection member or conduit 18, the nipple being cut at its distal end so as to form an opening for accommodation with the size of the opening of the ileal conduit. In some instances, the portion of the ileal conduit in connection with the conduit or projection member 18 is referred to as the ileal stoma. In any case, generally the stoma bud is that portion of the ileal conduit which projects above the surface of the skin, although the ileal conduit as described above refers not only to the conduit but also to the stoma portion as well.

As can be seen, the present invention eliminates the disadvantages found in the prior art. Irregularity of the stoma bud which can occur during surgery and as a result of scarring can also contribute to the urinary leakage problem found with prior art conventional devices. The use of a proper fitting projection member or nipple with the urinary collection device of the present invention allows the urine to be collected before it exits from the stoma. Thus the direct conduit or connection between the stoma or ileal conduit and collection bag eliminates the problems found in the prior art.

It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above apparatus without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
